An Irish-trainer horse bought for just £800 is the odds-on favourite for Saturday's American Grand National to take his career winnings to close to €500,000.
Hewick was purchased for the meagre sum by TJ McDonald and has been a revelation over fences.
Trained by John 'Shark' Hanlon, the seven-year-old won this year's Galway Plate to cap a season that also included a victory in the bet365 Gold Cup at Sandown in April.
